Abstract

PURPOSE:To perform rice husking work in the sanitary environment by constituting a suction air duct to the inside of a supporting member which supports a grain elevator in a wind sorting machine body and connecting this suction air duct to the suction part in the wind sorting machine body. CONSTITUTION:A husking part 1 performing rice milling operation and a sorting part for sorting blended rice are placed on a wind sorting machine body 22. A bucket type grain elevator 8 is provided to the lateral side part of this wind sorting machine body 22. A suction air duct 26 is constituted to the inside of a supporting member 25 which supports this grain elevator 8 in the wind sorting machine body 22. This suction air duct 26 is connected to the suction part in the wind sorting machine body 22. As a result, dust of the grain elevator 8 which is generated during rice husking sorting work is passed through the suction air duct 26 constituted to the inside of the supporting member 21 and sucked to the suction part in the wind sorting machine body 22 and removed. Dust generated from the grain elevator 8 is prevented from being scattered. Rice husking work is performed in the sanitary environment..
